An original signed marker sketch of Joe the guinea pig, sitting on a desk, playing a classic console.

The proceeds of this listing will go directly to help fund the development of Guinea Pig Parkour. Every $10 in profit will allow me to dedicate one more hour of development time to the game that month. You can help me get the game done sooner! Thanks for your support!

This marker sketch was made using Faber Castell Classic Pitt Artist Brush Pens, which use pigmented India ink, are lightfast, waterproof, permanent, and acid-free. It was drawn on Strathmore 300 Series Bristol Smooth paper, which is acid-free.

*Markers and pencil are shown to convey what materials were used to produce the sketch and are not included.
